若要更改PWM的占空比,调用`mcpwm_set_duty()`并以%为单位提供占空比的百分数值。如果您希望以微秒为单位设置任务,则可以选择调用`mcpwm_set_duty_in_us()`。可以通过调用`mcpwm_set_duty_type()`来改变PWM占空比的模式(占空比数值对应高还是对应低)。 **mcpwm_set_duty (in_us) ()** //设置占空比 ```c...

The motor speed will be proportional to the PWM duty. To vary PWM's duty call :cpp:func:`mcpwm_set_duty` and provide the duty value in %. Optionally, you may call :cpp:func:`mcpwm_set_duty_in_us`, if you prefer to set the duty in microseconds. Checking of currently set value...
